Graphicsmagick package error - meteor

Question

I'm trying to use the cfs:graphicsmagick package to generate thumbnails but all that is generated is an empty image.
When I start the server things look good:
I20150108-10:43:14.698(-8)? => GraphicsMagick found
I20150108-10:43:14.901(-8)? available
=> Meteor server restarted
but it seems gm is not available:
if (gm.isAvailable) {
console.log("gm is available");
}
and the console throws out an error:
Uncaught TypeError: Cannot read property 'isAvailable' of undefined

Answer 1

Look into docs, seems like the gm scope its just available on the server side, so there is not problem here, you are having the console.log, pretty find
now you can use, on the fsCollection like this
Images = new FS.Collection("images", {
stores: [
new FS.Store.FileSystem("images"),
new FS.Store.FileSystem("thumbs", {
transformWrite: function(fileObj, readStream, writeStream) {
// Transform the image into a 10x10px thumbnail
gm(readStream, fileObj.name()).resize('10', '10').stream().pipe(writeStream);
}
})
],
filter: {
allow: {
contentTypes: ['image/*'] //allow only images in this FS.Collection
}
}
});
remember gm its just available on the server, so use it on /server or use on if(isServer)
Try this
if (Meteor.isServer) {
if (gm.isAvailable) {
console.log("gm is available and this console.log was printed from my own code");
}
}
Tell me if works
Update answer
If you are declaring FS.collection on both server/client i recommend you declare collection on /lib/collection.js like this
//collections.js
Adopcion = new FS.Collection("Adopcion", {
stores: [
new FS.Store.FileSystem("images"),
new FS.Store.FileSystem("thumbs", {
transformWrite: function(fileObj, readStream, writeStream) {
// Transform the image into a 10x10px thumbnail
gm(readStream, fileObj.name()).resize('10', '10').stream().pipe(writeStream);
}
})
]
});
and on the same file make the subscription
//collection.js
//Subscribe
if(Meteor.isClient) {
Meteor.subscribe('Adopcion');
}
And now on /server/publish.js you only make the publish function
//Publish methods
Meteor.publish('Adopcion', function(){
return Adopcion.find();
});
With that there is no need of Meteor.methods({}) and the first thing meteor will load its the collection, and they will be available on both client/server
Take a look and tell me if works for you
